How do bad actors gain access to networks and bypass cybersecurity sensors?
BLUF:
Actors with malicious intent, also known as bad actors, employ a variety of techniques to infiltrate networks and bypass security measures.
Tactics used by attackers are constantly evolving. It's crucial to have robust cybersecurity measures in place, including firewalls, intrusion detection systems, and regular security awareness training for employees.
Common Steps: (5)
Identify vulnerabilities: They will scan the target network for weaknesses in system configurations, software, or even employee knowledge. This could involve exploiting outdated software, unpatched systems, or phishing emails to trick employees into giving up credentials.
Gain initial access: Once a vulnerability is identified, they will exploit it to gain a foothold on the network. This might involve using stolen login credentials, malware, or even physical access to a device.
Establish persistence: The attacker will try to maintain access to the system even after the initial breach. This could involve installing backdoors, creating new user accounts, or compromising legitimate accounts.
Elevate privileges: Once inside the network, attackers will often try to escalate their privileges to gain access to more sensitive data or systems. This might involve exploiting privilege escalation vulnerabilities in software or compromising accounts with higher access levels.
Cover their tracks: Throughout the process, attackers will try to avoid detection by security measures. This could involve techniques like erasing logs, disabling security software, or using anonymizing tools.
